anyone have a picture of a 2003 530i stock exhasut. or diagram. i need to see if its all single pipe or dual. the part im concerned about is if the pipe before th y resinator and the resinator behind that.

i am going to be doing an exhasut cutoff valve. with a switch inside the cabin so i can adjust the exhasut from straight pipe to a normal magnaflow 14816 with a nice tone. some of you might not like this, but i think it would be an amazing idea and if i pull this off allot of people will be doing it. its realy simple and cheap btw. wont even cost 300 dollars. il post pictures to show you guys how to do it and where i got the parts from. but i need to confirm the piping first. so someone please help me.
